This course emphasizes basic understanding of chemistry. Students will be introduced to theories and basic concepts of chemistry. The first part of the course explains the basic concepts of matter such as atoms, atomic structure and the periodic table of elements. In this section also there are calculations of basic concepts in chemistry such as mole, concentration and balance equation which is often used in any field of engineering, especially chemical and mechanical engineering. The second part of the course is more focusing on the physical and chemical properties of materials. Properties of matter in gases, liquids, and solids will be described. In addition, the reaction rate and the stability of matter in determining the direction the reaction will be explained. At the end of this course, students will master the theory, concepts and understandings of basic chemistry which are can be applied in the engineering field.
